Q. Only two forces act on an object (mass = 4.60 kg). (F = 68.0 N.) Determine the magnitude and direction (relative to the x axis) of the acceleration of the object.
A moving body undergoes uniform acceleration while travelling in a straight line between points X, Y and Z. The distances XY and YZ are both 40m. The time to travel from X to Y is 12s and from Y to Z is 6s.
A 72 person stands on a uniform ladder 4.5 long, that weighs 75. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force.
A force with a magnitude of 452N is used to bring an object with a mass of 56.0 kg moving at a velocity of 155m/s. How long will it take to bring the object to a full stop.
An old trick to find out if a train is coming is to put your ear on the rails of the track. Why is this more effective than just listening for the sounds the train makes in air.
IP A uniform electric field of magnitude 6 times 10^3 ;{rm{N/C}} points upward. An empty, closed shoe box has a top and bottom that are 37 cm by 28 cm, vertical ends that are 28 cm by 21cm, and vertical sides that are 21 cm by 37 cm.
At the beginning of the interval the astronaut is moving toward the right along the x-axis at 15.40, and at the end of interval she is moving toward the right at 5.40.
A baseball pitcher throws a fastball at a speed of 45.00m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it throughout an almost straight-line distance of 4.0 m. compute the acceleration; assume that it is constant ..
Express your reply in terms of the cylinder's radius r and the magnitude of the acceleration because of gravity g.
If a drop is to be deflected a distance = 0.28 by the time it reaches the end of the deflection plate, what magnitude of charge should be given to the drop? Imagine that the density of the ink drop is 1000 and ignore the effects of gravity.
A car travelling in a large circle passes by the motorcycle that is travelling in a straight line from North to South. Both of their speedometers read 10m/s.
A billiard ball is moving in the x-direction at 30 cm/s and strikes another billiard ball moving in the y-direction at 40.0 cm/s. As a result of the collision, the first ball moves at 50.0 cm/s, and the second ball stops. In what final direction d..
Most dentist in the United States are make as the majority of nurses are female. These differences show how different cultures define.
